No computer (IDE/ATAPI) connection needed. You might spend as much as $US10 for a new sample...less at a computer flea market. But...why? webpa |

The IDE bus is a universal thing. No pins are dedicated to a specific function, they are a databus. You have to set the control pins at the right time, and send the data on the data pins. I've not paid attention, but I think it's not even just a matter of setting up the data pins and sending a byte to start it playing and another byte to advance the track. Likely you have to send a packet of data for each function. This is why the only way (if there aren't suitable buttons on the CDROM drive) of controlling the drive is by adding a microprocessor, that controls the bus and sends the right commands to the drive over that bus. Using discrete logic will require too much circuitry.
